The Karhu Fusion 3.5 is a highly responsive, cushioned running shoe for neutral footed runners. Whether going easy or pushing the pace, the forward propulsion and plush cushioning make your run comfortable and playful. The 6mm heel-toe offset, shortened Fulcrum, and propulsion unit result in a swift and nimble underfoot experience. With every stride, the Fulcrum and propulsion unit will accelerate the transition from heel to toe-off, even during your easy runs. The Fusion 3.5 is an all-in-one shoe for the neutral runner with variety in their running workouts.

  • 6mm Drop
  • Shortened Fulcrum + Propulsion unit for an efficient stride
  • Highly cushioned AeroFoam midsole
  • Updated Ideal Knit mesh construction with improved breathability
  • M-Lock lacing construction ensures a secure midfoot

A true neutral trainer with a plush and propulsive ride, the Fusion 3.5 features the quickest “roll” in Karhu’s running collection.

The KARHU Fulcrum technology is designed to keep all forces going forward, reducing braking forces and using your body's natural energy to create a smoother ride. It's what we call the Rolling Effect. 


Fulcrum Technology provides: Balanced Cushioning, Increased Support, More Energy. The Fusion features a three-quarter length fulcrum.


Proprietary midsole foam: lighter, more resistant to temperature changes and better cushioning than EVA.


Seamlessly knitted upper patterns with zones for support, stretch, and breathability.


The M-lock side panels help secure the shoe around the foot while the inner construction remains straight.
